The DS-15 Stripped Billet Fixed Magazine Lower Receiver is the foundation of Dark Storm Industries' patented fixed-magazine AR-15 platform. CNC machined from domestic 7075-T651 billet aluminum, the receiver is manufactured without a magazine release and includes a factory-installed 10-round Magpul PMAG Gen M3.

Designed for custom fixed magazine AR-15 builds in restrictive states, the DS-15 billet lower retains compatibility with standard Mil-Spec AR-15 lower receiver components while incorporating DSI-specific features including an integrated oversized trigger guard, threaded bolt catch pin, and finger-grooved magazine well.

The Gen 2 receiver uses an M4-style low rear shelf trigger pocket and is precision CNC machined to tight tolerances. MIL-A-8625 Type III Class 2 hardcoat anodizing provides a durable base finish, with Cerakote available on select colors.
